Answer:
Step-by-step explanation:
Another way to solve would be to distribute first:
22 = 2(x + 6)
22 = 2x + 12
Subtract 12:
22 - 12 = 2x - 12
10 = 2x
Divide by 2:
10 / 2 = 2x / 2
5 = x

An ethanol railroad tariff is a fee charge for shipments of ethanol on public railroads. The Agriculture Marketing Service publishes tariff rates for railroad-car shipments of ethanol in the Biofuel Transportation Database. Assuming that the standard deviation of such tariff rates is $1150, determine the probability that the mean tariff rate of 500 randomly selected railroad-car shipments of ethanol will be within $100 of the mean tariff rate of all railroad-car shipments of ethanol.
Answer:
The appropriate response is "0.9476".
Step-by-step explanation:
The given values are:
Standard deviation,
[tex]\sigma=1150[/tex]
Randomly selected railroad-car shipments,
n = 500
As we know,
⇒ [tex]\sigma \bar{x}=\frac{\sigma}{\sqrt{n} }[/tex]
On substituting the values, we get
⇒ [tex]=\frac{1150}{\sqrt{500} }[/tex]
then,
⇒ [tex]=P(-1.94<Z<1.94)[/tex]
⇒ [tex]=P(Z<1.94)-P(Z < -1.94)[/tex]
On using the table of P, we get
⇒ [tex]=0.9738 - 0.0262[/tex]
⇒ [tex]=0.9476[/tex]

Suppose a is an irrational number
and is a rational number. Can
their sum be rational? Explain your
answer.
Answer:
The sum of a rational number and an irrational number is irrational
Step-by-step explanation:
By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats. If you add a non-repeating, non-terminating decimal to a terminating decimal, you still have a non-repeating, non-terminating decimal. If you add a non-repeating, non-terminating decimal to a repeating decimal, you will no longer have a repeating decimal.
Example:
[tex]3+\sqrt{5} = 3+2.236067977...=5.236067977....[/tex]
1. Find the sum of the measures of the interior angles of a convex 11-gon.
Answer:
The measure of the sum of interior angles of a 11-gon is [tex]1620^{o}[/tex].
Each interior angle is approximately [tex]147.273^{o}[/tex].
Step-by-step explanation:
A convex polygon has the measure of each interior angles to be less than [tex]180^{o}[/tex].
But,
sum of interior angles of polygon = (n - 2) x [tex]180^{o}[/tex]
where n is the number of sides of the polygon.
For a convex 11-gon, we have;
sum of angles of a 11-gon = (11 - 2) x [tex]180^{o}[/tex]
= 9 x [tex]180^{o}[/tex]
= [tex]1620^{o}[/tex]
Sum of angles of a 11-gon = [tex]1620^{o}[/tex]
To check: convex polygons' interior angles are less than [tex]180^{o}[/tex].
so that,
each interior angle of 11-gon = [tex]\frac{1620}{11}[/tex]
= [tex]147.273^{o}[/tex]
An irregular hexagon has angles that measure the following. Angle 1: 2x + 15 Angle 2: 9x - 3 Angle 3: 77 Angle 4: 8x + 8 Angle 5: 13x Angle 6: x - 4 What is the value of x?
Answer: 19
Step-by-step explanation:
1) You combine like terms with all the angles
Ex. 2x + 15 + 9x - 3 + 77 + 8x + 8 + 13x + x - 4, which equals 33x + 93
2) You set up an equation using the formula for the sum of the interior angles
Ex. 33x + 93 = 180(n - 2)
3) Since a hexagon has 6 sides, n is 6
Ex. 33x + 93 = 180(6 - 2)
4) Solve like a regular equation
Ex. 33x + 93 = 180(6 - 2)
33x + 93 = 720
- 93 = - 93
33x = 627
- Divide 627 by 33
x = 19

4(2x - 3) = 6x + 2
Answer:
x =7
Step-by-step explanation:
Let's solve your equation step-by-step.
4 ( 2x − 3 ) = 6x + 2
Step 1: Simplify both sides of the equation.
4 ( 2x − 3 ) = 6x + 2
( 4 ) ( 2x ) + ( 4 ) ( −3 ) = 6x + 2 ( Distribute )
8x + −12 = 6x + 2
8x − 12 = 6x + 2
Step 2: Subtract 6x from both sides.
8x − 12 − 6x = 6x + 2 − 6x
2x − 12 = 2
Step 3: Add 12 to both sides.
2x − 12 + 12 = 2 + 12
2x = 14
Step 4: Divide both sides by 2.
2x / 2 = 14 / 2
x = 7

1. The perimeter = 120 m; length = 45 m ; breadth = ____
2. Perimeter of a rectangle = 250 m; breadth = 50m; length = _____
1) to find perimeter we multiply length and breadth so to find breadth we divide the perimeter by the length. which means, 120 divided by 45 and its 62.5 so the answer for the 1st question is 62.5
2. if we multiply length with breadth to find perimeter, just like the first one we divide the perimeter by the breadth. which means, 250 divided by 50 and it will be 5
